I have just noticed people tend to do this when I'm on the bus and using my SP 3 to do assignments or review lectures. For the past 6 months that I've been using the same bus, no one had brought out their laptops. But on 2 out of 3 occasions that someone sat next to me while using my SP3, the person next to me also brought out their laptops. Is this some sort 'who's got a bigger dick' game that laptop users practice? lol. I've always made sure to return the gesture by showing off that mine is touch screen or fold it up to show how thin it is and slip it into my bag if they don't get off too soon.
